What changes an ER claim in Mississippi.
Every Mississippi rule on file, each linked to its primary source: state surprise-billing law, Medicaid ER policy, Medicaid managed care, the Blue plan and the Medicare contractor.
| Rule type | Date | What it says | Source |
|---|---|---|---|
| State surprise-billing law | Dec 2021 | Mississippi has no state out-of-network rate law; the federal No Surprises Act IDR process decides out-of-network ER professional payment for state-regulated plans, with CMS and the state enforcing the outcome. | Source |
| Medicaid managed care | Nov 2025 | Magnolia Health (MississippiCAN MCO) policy CC.PP.051 covers ED visit E/M: high-complexity levels (e.g. 99285) need documented extensive diagnoses/data and high risk, or claims face payment delay, disallowance, records requests or post-payment review. | Source |
| Blue plan | Jan 2011 | BCBS of Mississippi modifier guide (rev. Jan 2011, still posted): E/M needed to perform a procedure is bundled into the procedure; a same-day E/M is paid only with modifier 25 when significant and separately identifiable (e.g. with labs, x-rays, observation, or unrelated diagnoses). | Source |
| Medicare contractor | Jun 2026 | Medicare Part B ER professional claims in Mississippi go to Novitas Solutions, Jurisdiction H (JH). CMS re-awarded JH to Novitas on 25 Jun 2026; contract runs to May 2033. | Source |
How we bill Mississippi ER visits.
The same four-step workflow we run for emergency medicine and hospitalist groups billing from their hospital system.
Hospital feed and registration
Demographics, insurance and the attending physician arrive from the hospital system daily. Gaps go back to registration as clarification requests, not guesses.
MDM levels and critical care minutes
ED visits 99281-99285 are coded on medical decision making only. Critical care is 99291 for 30 to 74 minutes and 99292 from 104 total minutes, on documented time.
Modifier 25 and enrollment check
A separately identifiable E/M on the day of a procedure carries modifier 25 with its own documentation. The rendering physician is checked against the payer roster before release.
Submission, remit and NSA/IDR
Professional claims go out with place of service 23. Out-of-network ER claims follow the No Surprises Act: in-network cost share only, open negotiation, then federal IDR.
